OEM/ODM Power Plant Marine High Pressure Forged Steel Gate Valve Class 800

Product Description

We manufacturing capabilities for API Forged Gate valves include 1/2"-2", ANSI Pressure class 150#-2500#. Materials of construction include Carbon Steel, Stainless Steel, Alloy 20, and other exotic materials.

Forged gate valve is manufactured from the finest quality components and under the firm direction of experienced quality controllers. These are engineered using the best quality components and following international industrial standards.

The forged steel gate valve is designed for API602 and has an elevated stem outer screw and yoke.  Dedicated for both flow directions isolation.

Forged gate valves are great for processing liquids in pipelines. These forged gate valves provide a favorable tight shutdown both in horizontal and vertical situations.

Forged gate valves also offer a small amount of control and are used to throttle steam, gas or liquids. Easy to operate and the preferred choice over ball valves by engineers to isolate trapping stations.




High-pressure gate valves have low-pressure drop when they are fully open. This helps to save pumping energy.
They are bi-directional. This property allows the valve to transport fluid in either direction of the piping system.
They are of high strength, allowing them to operate under high pressure and temperature.
These valves are versatile in the application as they are used in many industrial applications.
They are free from fluid leakage.
High-pressure gate valves are highly reliable for on and off fluid flow.
They can be automated or they can be operated manually.



High Pressure Forged Steel Gate Valve can be operated by pneumatic actuator,electric actuator,intelligent control head and manual operation.There are a variety of standards provided to customers,such as,DIN,API,ANSI,and so on

A high-pressure gate valve operates manually or through automation. The basic working principle remains the same whether the valve is manual or automated: the actuator rotates the stem to start/stop flow. The valve starts when the actuator rotates clockwise for several turns. As such, the stem converts the rotary motion to linear movement.

This linear motion causes the valve disc to move upwards, leaving the valve open. With the valve open, fluid starts flowing through the valve. The valve stops flow when the actuator is rotated counterclockwise, forcing the stem and disc to move downwards. As such, the disc seals the valve's central hole where liquid flows through. At this state, the valve is closed, and there is zero fluid flow.







These valves are used in thermal power plants to control the flow of steam and water at high temperatures without damaging valve seats.
They are used in municipal water supply over long distances since they have a low-pressure drop.
High-pressure gate valves are used in the transport petroleum and petroleum products.
High-pressure gate valves are used in steel manufacturing plants.
They are used to feed boiler systems.
They are used in marine applications.
They are used in transportation of chemicals and water.
